This invention relates to a toilet and especially to a. device of thischaracter which is particularly intended and designed for-use onpassenger carrying 'vehicles' such as long distance buses but it isunderstood, of course,

. that a toilet in accordance with this invention may be used in 'anymanner for which u same may be found adapted and desirable.

An important object of-the invention is to provide atoilet of theaforementioned char-i acter which willbe very 'compact in-,construcy`tion and arrangement,`thereby requiring 'a minimum of'space in thevehicle in which 7same is installed. y

j Another very importantobject of the invention is to provide in amanner as hereinafter set forth, a toilet of the character devide a'toilet of the character set forth which will be simple in construction,strong, durable, efficient and reliable in operation, and which jmay lbe manufactured and installed at low cost.

jects and advantages of the invention will b'ecome apparent fromv astudy of the following specication, taken in onnection with theaccompanying drawings herein like characters .of reference designatecorresponding parte throughout the several views, and wherein and partlyin vertical section through at'oilet constructed in'accordance with thepresent in-f vention.

Referring `now tothe drawings in detail, it

will be seen that 'the'reference numeral 1 des- .ignatespa housing ofsuitable shape and size havingan open` side disposed' in abutting envA11 of the foregoing imagen further 0b;

gagementwith a wall2 of the vehicle or'other l be had to theJ interiorof the housing 1 for a purpose which willbe more fully hereinafter setforth.`-/Abovef the housing 1 the wall 2 is further provided with arecess or depression 4, the'purpose of which willalsolbe presentlysetforth.

A bowl 5 having a rim portion 46. thereon is mounted by \a hinge 7 foswinging move- "ment 1 n`a vertical plane on the housing 1 toward andaway from the recessed portion 4:l of the wall 2. The hinge constructionwhich 4 connects the bowl 5to the hosing 1 is such that the downwardyswinging movement of said bowl will be arrested when "the bowl is ure 1,When the boy l is swung upwardly,

, the rim portion 6 thereof is adaptedto enter the recess 4 of the wall2, as seen in Figure 2 l Yof the drawings.'

An arcuate, telescopic sectional pipe 8 extends from the rear upperportion of the bowl 5 downwardly into the housing 1 through an openingprovided therefor in the top ofsaid `housin l and terminates in an elbow9 vwhich `downwardly'directed discharge rbranch which is' detachablyconnected to the tapered neck 10 of aseptic tank 11 which is removablydisposed in the housing 1 in a manner to provide Figure 1 1s a viewpartly 1n side elevatlon afleakproof joint through the mediumof asuitable couplingy clamp 12 whichisillus'- tratedto advantage in Figure3 ofthe draw- 1n nected Jaws havin suitable means on their goove for the'reception ofthe tapered 4nec Fi re 1 of the drawings.

e reference numeral 13 designates a backrest vwhich is mounted forvertical 'swilging movement in a direction at right angles to 10 and thetapered '.iiange onl the lower end of the elbow 9, as best seen in i l4is rigid y mounted inthe-housing. The elbow" i A gs. It will be seenthat the clamp 12 comy prlses a pair of complementary,pivotallyconmounted on the housing 1 coaxially with the bowl 5 and isoperatively connected to said bowl in a manner to yieldingly -urge sameupwardly to raisedor inoperative position as at 17. A cableP18 has oneend connected to the operator 16 for actuation thereb and is .trainedover suitable pulleys 19 an has its other end connected to thefree endportion of the arm of the back rest 13, as illustrated I to advantage inFigure 4 of thedrawings.

Thus, when thel operator 16 swings the bowl 5 to its raised orinoperative position,'the

back rest 13 will, through the medium of the cable 18, beswugng upwardlyto 'ts inoperative position as indicated in bro en lines in Figure4 ofthe drawings' to permit the rim.,

portion 6 of the bowl to enter the recess or depression 4 in theWall 2.

The reference numeral 20 designates a water/ storage tank or reservoirwhich is mounted on the wall 2 or on any other suitable structure@ abovethe back rest 13.' A measuring container 21 is connected to the lowerend of the reservoir 2 0 by a valved couplin 22. The reference numeral23 designates a u'sh pipe which is connected to the measuring'con-talner or tank* 21 bya valve `24. The flush pipe 23 terminatesin asubstantially U-shaped lower end-portion which is formed to accommodatethe vfree end portion of the bowl 5 when said bowl is in its raisedorinoperative position, the vfree end portion of the Hush pipe projectinginto the bowl in the manner illus.- trated to advantage in Figure 2 ofthe drawings.

operation in the form of arod 25 having its lowerend pivotally connectedto one end of a pivotally mounted bell crank lever 26. A suitable spring27 normally maintains the valve 24 in its closed position and the upperyvalve 22 in its open position.

iso

The reference numeral 28 designates an air valve which isconnected y apipe 29 with the upper lend of the measuring container or tank 21. Theair valve 28 is connected by a vplpe 30-.with the air brake system ofthe vehicle or with any other suitable source of air pressure supply.The valve head of the air valve 28 is mounted on a reciprocating stem 31having a coil springoperatively connected thereto for ,ieldingly urgingthe valve` toward itsclosed position. On its lower end the'valve stem 31is providedl with suitable` spring controlled pivoted means disposed inthe path of the upper end of the rod 25 for engagement and actuationthereby. in a manner to open the valve 28 when the rod 2.5 is movedupwardly but to permit downward movement The valves v2 2 and 24 areprovided with common actuating means for simultaneous the reservoir 20while the bowl is in use.

"remvin the coupling clamp '12.

of Ithe rod 25 independently ofthe valve 28.Y In use, the bowl 5 is swundownwardly from the position illustrated 1n Figure 2 to 'state that thetelescopidarcu'ate pipe 8 is disposed concentrically withl the .axisabout which thef'bowl 5 swings. After bein used,- the bowl 5 is againswung upwardly luy the" 80 operator 16, the sections of the ipe 8telescoping Within each other and t e cable 18 again swinging the backrest13 outwardly and upwardly to its inoperative position to permit therim portion 6 of the bowl to enter 85 the recess or depression 4 in thewall 2. When the bowl enters thefrec'ess or depression 4, the upper endportion thereof engages the free end portion of the bell crank lever 26in a manner-to swing, the rod 25 upwardly and 90 open the valve 24 andclose the valve 22.' This same movement ofcthe vrod 25 opens air valve28 to admit air under pressure into the upper end of the measuring tankor co1npart-' ment 21 andthe water therein will be dis- 95 chargedthrough thepipe23 with considerable force into the upper portion of the.bowl

5 in a manner tothoroughly flush said bowl, the .flushing water passingdownwardly through the'telescopi'c pipe 8 intothe septic tank 11.' Itwill be seen that the pressure of the air is addedto the force ofgravity on the flushing water which passes downwardly through the pipe23.A It may be well to here vstate .that when thesbowlf is swungdownwardl for use, the spring-27closes the valve 24 and opens the valve22 ina mannen-'to permit the measuring tank 21V to be illedfrin viously,when the bowl is not in use and has lSHO been flushed thev measuringtank 21 is empty and the valve 42,2 is closed'. The tank 11maybe'expeditiously removed and replaced through the, hinged door 3' byvIt is elieved that the lmany advantagesofatoilet constructed inaccordance with this invention will bev readily understood, and althoughthe'preferred embodiment of the invention is as illustrated anddescribed, it is to be understood that changes in the details lofconstruction, and -the arrangement of i parts ma lbe resorted to withoutdeparting from th s irit of the invention as claimed. 4
